6 FAQs about [Energy storage heat exchange system price]

How much does thermal energy storage cost?

In our base case, the cost of thermal energy storage requires a storage spread of 13.5 c/kWh for a 10MW-scale molten salt system to achieve a 10% IRR, off of $350/kWh of capex costs. Costs are sensitive to capex, utilization rates, opex, electricity prices and round trip losses. The sensitivities can be stress tested in the data-file.

How much does energy storage cost?

The challenge is that medium- and long-duration storage technologies require an order of magnitude lower cost per energy storage capacity than short-duration ones: energy storage costs of approximately 35, 6 and 2.6 €/kWh are needed for storage durations of 10, 50 and 100 h, respectively .

How much does a heat exchanger cost?

The capex costs of heat exchangers are estimated at $200/m2 on average, but this varies between $100/m2 and $500/m2 depending on the thermal swing and corrosiveness of fluid streams being heat exchanged. Some systems use stainless steel and others require high grade nickel steels. Plate-fin designs are 2x more efficient than shell-tube designs.

Why is heat exchange important?

But heat exchange becomes increasingly important to accelerate efficiency gains in the energy transition. Heat exchangers are used to increase the efficiency of thermal power plants (60% of combustion heat ends up in the exhaust gas!), for thermal energy storage, or to lower the energy penalties from CCS absorbers.

Should thermal energy storage systems be used to convert heat back to electricity?

Even if there is an efficiency penalty when converting heat back to electricity, the low cost of thermal energy storage (TES) systems is an important advantage. Besides, not always the heat stored in a TES system needs to be converted to electricity, as heat corresponds to about 50% of the global energy demand.

How long does an energy storage system last?

The 2020 Cost and Performance Assessment analyzed energy storage systems from 2 to 10 hours. The 2022 Cost and Performance Assessment analyzes storage system at additional 24- and 100-hour durations.
